It could be what you think. But I think it's probably more likely that it's a bad picture of an orange latticinio. Either way, I wouldn't mind seeing a better picture too!
I look for them fairly regularly on ebay and don't find them very often. Nice examples, of course, turn up even less often than that. I don't know that they would be considered HTF by some collectors, but I consider them pretty HTF.
Me too, although I've had many more green / yellow ones. But the oranges have certainly been all over the place, including some filiments in some German sparklers (not many, but they're there, much to my surprise).
